Definitions

  • the present invention refers to a net for waters to intercept, collect and/or recover flat products, in particular structures consisting of open-cell expanded plastic and soaked with polluting substances, on/from the surface of the water, according to the precharacterizing clause of Claim 1 .
  • Known nets used at sea and, where applicable, also on inland waters are excellent means for catching fish below the water surface;
  • Such nets so-called fixed nets, are either rigid or flexible in structure, provided with a ballast line below the water surface and an appropriately adjusted float line on the water surface, which causes this fixed net to assume a more or less vertical position in the water.
  • Rigid fixed nets stand in the water similar to a wall and are nearly motionless in the swell of the sea, which results in the waves rolling over the net. In the swell of the sea, while flexible fixed nets move up and down in unison with the waves, big or high waves will likewise roll over the net.
  • the objective of the present invention therefore is to create a net of the initially mentioned kind that can be pulled through the water in a tightened manner similar to a fixed net which, however, is allowed to move up and down in unison with the swell of the sea in such a way that an upper part always remains above the water/wave surface even in heavy seas and, therefore, on high waves.
  • Claim 1 the features stated in Claim 1 are provided in a net for waters to intercept, collect and/or recover flat products of the initially mentioned kind.
  • the measures according to the invention ensure that the flexible part of the net is always at a certain level above the water surface even if there are considerable waves in the water.
  • the design of the net results, in a cross-section view, in a roughly tunnel-shaped arrangement of the net in the water, with its basic walls standing upright in the water and its curved intermediate section being located above the water surface and protruding from it by a certain amount. Since the flexible part of the net provides wind and waves only with a little target, it is avoided that the curved part of the net is run over by the waves. Even if this curved part is distorted by the waves, a sufficient portion will still remain above the wave surface, which means that this curved part is practically not rolled over by the waves. This also means that the flat products to be recovered remain in the zone enclosed by said net.
  • the features according to Claim 2 results in an asymmetric arrangement of the net in the water, which means that the flat products are mainly held by the fixed net part and the flexible net part reacting considerably more quickly can move up and down in unison with the waves.
  • the features according to Claim 3 may be provided there to advantage.
  • the features according to Claim 4 result in a further support of the measure to ensure that the curved or distorted part of the flexible net part always remains above the water or wave surface, i.e. always protrudes from the water.
  • the features according to Claim 5 are provided there to advantage.
  • the net described so far consists of a fixed net part and a flexible net part arranged behind it which is put up in a curve above the water surface owing to the design of its free longitudinal edge with ballast and float units. It may happen that the net, which, in a cross-sectional view, looks like a walking-stick, does not withstand all conceivable conditions at sea below and above the water surface such as gale-force storms. In order to avoid the danger that the flexible net part tips over or opens up, the features according to Claim 9 are provided. This results in a net which keeps its desired active position below and in particular above the water surface under all conceivable conditions in the water.
  • the features according to Claim 10 are provided, which additionally prevent the net as a whole from positioning itself mainly flat in the water.
  • the features according to Claim 11 are provided to advantage, resulting in a symmetric position of the net in the water and above the water surface.
  • Another advantage arising from this embodiment with said option consists in the desired position of the net in the water being maintained even if water pressure builds up against the net from both external sides such that only the clear width between the longitudinal edges arranged opposite to each other of the flexible net part and/or of the two fixed net parts is changed.
  • Claim 13 To facilitate the uncoiling and coiling of the net similarly to conventional fishery nets, the features of Claim 13 are provided. They cause the net to lie flat as it is removed from the water because of the flexibility of the flexible net part while the two fixed net parts position themselves either nearly parallel to the flexible net part or just slightly sagging.
  • the flexible net part is designed according to the features of Claim 14 .
  • a slack net design as it is used in fishery can be used which can be readily converted to a net part that can be bent to the desired direction.
  • the features according to Claim 15 and/or 16 are provided to advantage.
  • Such flexible solid or hollow bars made from a wide variety of sections such as round sections, rectangular sections, etc. have to be made of plastic, glass fibre, carbon-fibre-reinforced plastic or the like.
  • the design of the net parts can be further facilitated and the ease of net uncoiling and coiling outside the water is further supported provided the features according to Claim 17 are provided. Unlike where exclusively buoys are used as float units, it is still possible to coil the net flat on a net drum.
  • the features according to Claim 18 and/or 19 may provided to advantage.
  • the present invention moreover refers to a process to remove pollutant layers by means of one or more said nets.
  • the features according to Claim 25 are provided.
  • FIG. 1 Typical cross-sectional view of a net for waters according to a first embodiment of the present invention, floating in water,
  • FIG. 2 Typical partial perspective view of the net according to FIG. 1 , in a coilable flat initial state
  • FIG. 3 Typical sectional views of nets according to FIG. 1 , in various operating states in water,

  • FIG. 6 Another embodiment of one or more placed nets according to FIG. 1 .
  • FIG. 7 Typical cross-sectional view of a net for waters according to a second embodiment of the present invention, floating in water,
  • FIGS. 8A-8C Partial top views and side views, according to arrow IIB of FIG. 2A , of the net outside the water and in the state in which it can be coiled outside the water, and
  • FIG. 9 For comparison with the cross-section of FIG. 1 , the shape of a net floating in the water and exposed to considerable transverse pressure by the water, in a simplified typical representation.
  • Net 10 , 110 shown on the drawing according to two embodiments of the present invention is destined for waters 12 , 112 , in particular for seas, and is used to intercept, collect and/or recover flat products 11 , 111 , in particular of open-cell expanded plastic such as PP or PU or PE open-cell foam, which are soaked with polluting substances such as oily layers, e.g. oil patches, thin layers of oil or liquid plastic, e.g. styrene, as such pollutant layers are removed from the water surface.
  • open-cell expanded plastic such as PP or PU or PE open-cell foam
  • net 10 has fixed net 13 made of rigid or flexible material and, connected to it, another net part having the shape of grid net 14 and consisting of flexible material which is bending-elastic particularly in transverse direction.
  • Fixed net 13 which is composed of single net layer 16 , has ballast line 18 , consisting of or containing lead-bearing material, attached to one of its free longitudinal ends 17 .
  • ballast line 18 consisting of or containing lead-bearing material, attached to one of its free longitudinal ends 17 .
  • At upper longitudinal end 19 which develops into grid net 14 and is connected to the latter, two parallel float lines 21 and 22 are provided between which pull rope 23 is arranged longitudinally and which float on water surface 15 .
  • Grid net 14 in the embodiment has another two net layers 27 and 28 which lie on net layer 26 and are connected to the latter.
  • the other net layers 27 and 28 form an integral part and are laid out in meanders. It is obvious that net layers 26 to 28 may likewise form an integral part and be laid out in meanders.
  • Grid net 14 which, like fixed net 13 , is provided with, or connected to, float lines 21 , 22 and pull rope 23 in connecting or overlapping area 19 , has its far free end 31 provided with ballast line 32 which, like ballast line 18 , consists of lead or at least partly consists of lead-bearing material.
  • ballast line 32 which, like ballast line 18 , consists of lead or at least partly consists of lead-bearing material.
  • grid net 14 is provided with a float line unit 33 which consists e.g. of three single float lines and floats on water surface 15 . The distance from this float line unit 33 to ballast line 32 of grid net 14 is clearly shorter than its distance from float lines 21 , 22 in connecting area 19 of grid net 14 and fixed net 13 .
  • grid net 14 has further single float lines 36 which are preferably evenly spaced side by side and protrude from water 12 along curved grid net 14 .
  • FIG. 2 shows the design and the flat state of net 10 composed of fixed net 13 and grid net 14 in which state net 10 can be coiled on a drum and uncoiled from this drum 41 on ship 40 and placed in water 12 according to FIG. 4 .
  • net 10 While being placed according to FIG. 4 , net 10 , initially being in a flat state according to FIG. 2 , takes a tunnel-like shape according to FIG. 1 , which is also obvious from FIG. 4 .
  • This change in state is a result of the arrangement of ballast lines 18 and 32 and float lines 21 , 22 , and 33 , which cause fixed net 13 and area 34 of grid net 14 between float unit 33 and ballast line 32 to turn upright.
  • ballast lines 18 , 32 is adjusted to related float line 21 , 22 and float unit 33 .
  • curved section 37 results automatically between float lines 21 , 22 and float line unit 33 owing to the bending elasticity of net layers 26 , 27 , 28 .
  • the measure of bending elasticity is dependent on the number and the design of net layers 26 , 27 , 28 .
  • FIG. 3 is a typical view of how net 10 , which has a roughly tunnel-shaped cross-section, moves and behaves under the influence of waves in water 12 . Accordingly, curved section 37 is always kept above water surface 15 even under wind and wave attack, as shown with arrow A, and in particular when curved area 37 is distorted. This prevents most of the waves and thus soaked flat products 11 from rolling over.
  • FIGS. 5 and 6 show how surface zones of polluted water are isolated by means of one or more nets 10 .
  • net 10 is subdivided into net sections 43 which are connected to section-shaped hollow part 44 where fixed net 13 and grid net 14 are connected, but are held together directly in the other areas.
  • net 10 consisting of two net sections 43 can, according to FIG. 5B and FIG. 5C , be used by means of ship 40 and buoy 39 or by means of two ships 40 to enclose the affected water zone.
  • V-shaped net sections 43 are connected directly to neighbouring ones and are held by anchor 46 , for instance, whereas net sections 43 are interconnected by extraction hollow section 44 .
  • net 110 has a first fixed net 113 , flexible net part 114 which is integrally connected to it and can put up itself in a curve, and a second fixed net 120 integrally connected to flexible net part 114 .
  • Net 110 which is thus composed of first fixed net 113 , flexible net part 114 and second fixed net 120 forming an integral part, for instance, is manufactured preferably in the form of a fishing net of slack material known from the fishing technology, in which only the mesh width can be adjusted to the application described above.
  • Net 110 may therefore be one hundred or several hundreds of meters in length as it is common in the fishing technology, its width being different insofar as first fixed net 113 , which has a width corresponding to that of fishing nets, is widened by flexible net part 114 , on the one hand, and by second fixed net 120 , on the other. It is obvious that net parts 113 , 114 , and 120 can each be manufactured separately and subsequently connected to each other at their longitudinal edges. All net parts 113 , 114 , and 120 are single-layer net arrangements.
  • the two fixed nets 113 and 120 have their free lower longitudinal ends 117 and 124 according to FIG. 7 connected to each other and are provided there with common ballast unit 118 taking the form of, for example, a ballast line provided with lead balls.
  • the two joined and connected lower longitudinal ends 117 and 124 are also connected to longitudinal pull line or pull rope 125 .
  • Flexible net part 114 which, considering its active position, will hereinafter be referred to as curved net 114 , is elastic, i.e. flexible, over its width owing to the use of flexible bars 150 .
  • Flexible bars 150 are preferably and provided evenly spaced over the length of curved net 114 .
  • Flexible bars 150 may be firmly connected to curved net 114 at certain distances.
  • Flexible bars 150 may also be threaded through the meshes of curved net 114 so as to achieve an appropriate connection of curved net 114 and flexible bars 150 . In this case it is sufficient to connect the ends of flexible bars 150 to curved net 114 e.g. by means of cable ties.
  • flexible bars 150 are made of nonmetallic material such as plastic or laminated plastic, e.g. plastic reinforced with glass fibre or carbon fibre.
  • the cross-section of flexible bars 150 may be chosen according to the desired flexibility, for example round, rectangular, oval or the like; they may also be hollow or of solid material or have their cross-section filled in any other fashion desired.
  • the material used is chosen so as not to be affected by pollutant attack.
  • Curved net 114 additionally has its longitudinal ends, which are connected to the two fixed nets 113 and 120 , provided with ballast units 132 and 135 which may be composed of ropes provided with lead balls, for instance.
  • ballast units 132 and 135 which may be composed of ropes provided with lead balls, for instance.
  • float units 121 and 133 are provided which, in the embodiment shown, consist of several single extended plastic strips 151 which are arranged parallel to each other.
  • the material provided for these float strips 151 is closed-cell expanded plastic. Five or six such plastic strips 151 are arranged parallel to each other in the embodiment, thus defining float units 121 and 133 .
  • Plastic strips 151 are arranged longitudinally to curved net 114 and firmly connected to this net, e.g. threaded through the meshes of curved net 114 alternatingly and kept in place at their ends. It is obvious that other fastening options or arrangements may be provided, e.g. coating of these longitudinal edges of grid net 114 with appropriate expanded plastic. This material is likewise chosen so as not to be affected by pollutant attack.
  • the two fixed nets 113 and 120 are equal in width whereas, according to FIG. 8B , the width of grid net 114 is either equal to the sum of the widths of the two fixed nets 113 and 120 or somewhat less than the fixed-net widths together.
  • net 110 when withdrawn from the water, is mainly flat. This is due to the fact that grid net 114 automatically returns to a flat position outside the water owing to its own and the bars' flexibility so that the two fixed nets 113 and 120 being pulled likewise change from their V-shape to a mainly flat position and sag somewhat in relation to flat grid net 114 depending on the relationships of width involved.
  • Net 110 in water 112 usually remains in its position as shown in FIG. 1 . Only when water pressure builds up at both sides of net 110 , which is the case particularly at sea, will net 110 take the cross-sectional shape as shown in the typical view of FIG. 3 without the desired active position of net 110 in water 112 as a whole being changed.
  • the design of net 110 implies that only the V-shape of fixed nets 113 and 120 as well as the curved shape of curved net 114 is changed as a result of compression. This does not affect the use or application of net 110 .
  • flat products 11 , 111 consisting of open-cell expanded plastic, e.g. PP or PU or PE open-cell foam, are placed below the water surface so that they can soak the polluting substances on the water surface.
  • open-cell expanded plastic e.g. PP or PU or PE open-cell foam
  • one or more nets 10 , 110 being in the flat state are uncoiled from drum 41 on ship 40 and placed on water surface 15 , 115 , during which process net 10 , 110 takes a tunnel shape.
  • two or more net sections 43 are connected to each other by means of extraction hollow section 44 and the free ends of outer net sections 43 are connected to buoys 39 and anchor 46 and/or ships 40 by means of pull ropes.
  • One or two ships 40 may circle around the polluted zone on water surface 15 or the net sections may be placed in zigzags off the coast. Soaked flat products 11 , 111 are sucked through hollow sections 44 and disposed of or treated in a station.
